Description

A kind of method and facility regulating sunlight greenhouse strawberry root circle environmental temperature
Technical field
The invention belongs to a kind of facilities environment management domain, refer to that one arranges pipeline, for method and the facility of Summer and winter double regulation control sunlight greenhouse strawberry root circle environmental temperature on high-level cultivating groove especially.
Technical background
Fragaria rose family Fragaria is herbaceos perennial, and because it has higher economic worth, wide adaptability, is applicable to industrialized agriculture whole year production.Simultaneously because strawberry is shallow root plant, the requirement of root system to environmental condition is more responsive, particularly to the requirement of temperature, shows as neither high temperature resistance, also not low temperature resistant.The critical temperature of strawberry root growth is 2 ~ 5 DEG C, can be subject to freeze injury, can freeze to death when-12 DEG C-8 DEG C time.The optimum temperature of root growth is 13 ~ 23 DEG C, and more than 25 DEG C root growths are slow, and temperature is the highest is limited to 35 DEG C.Therefore, in strawberry management, measure of effectively heating must be taked winter to increase ground temperature, to ensure root system safe overwintering, and promote the growth of root system; Summer high temperature should take effective cooling measure period, to reduce ground temperature, makes root normal growth.
Winter, because greenhouse by solar heat area is large, if adopt traditional hot water pipeline mode of heating to regulate greenhouse by solar heat ambient air temperature, be difficult to reach the effect of overall intensification, and extremely easily there is localized hyperthermia, topical hypothermia, causes strawberry to grow inconsistent, even occurs the phenomenon of wilting.Simultaneously when manually heating, because the rising of ground temperature exists significantly delayed, very easily cause when temperature reaches strawberry suitable growth temperature, root ring temperature is still in the phenomenon of lower value, this phenomenon causes strawberry improving activity of root system to reduce, and nutrient absorption slows down, and can not meet the demand to acrial part nutrition supply, cause strawberry poor growth, even stop growing.Summer high temperature period, the greenhouse by solar heat temperature on daytime and ground temperature have all exceeded the preference temperature of strawberry, and strawberry growth is suppressed.If adopt traditional wet curtain-blower fan circulation temperature lowering mode to regulate greenhouse by solar heat ambient air temperature, the effect reducing temperature can be reached, but meanwhile, the air humidity in greenhouse by solar heat can increase rapidly, be unfavorable for that strawberry carries out photosynthesis and very easily causes the generation of damage by disease and insect.Therefore, in actual production, in greenhouse by solar heat, the growth of variation phenomenon to strawberry of this temperature and ground temperature is very disadvantageous, improve this present situation, and the lifting of the level of environment conditioning ability is required technological approaches.
Summary of the invention
The object of this invention is to provide a kind of method that can be used for Summer and winter double regulation control sunlight greenhouse strawberry root circle environmental temperature, adopt the mode of directly arranging pipeline on the cultivation matrix of strawberry high-level cultivating groove, by regulating water temperature direct regulation and control strawberry root circle environmental temperature, reach in the difficulty reducing regulation and control, temperature adjusting effect is improved on the basis of minimizing energy resource consumption simultaneously.
For achieving the above object, the present invention takes following technical solution:
Regulate a method for sunlight greenhouse strawberry root circle environmental temperature, it is characterized in that: adopt and directly on the cultivation matrix of strawberry high-level cultivating groove, arrange pipeline, pipeline distance strawberry 5-8cm; Winter, water is filled in advance to normal-pressure hot-water boiler, heating water temperature to 55 ~ 60 DEG C, open water pump, current flow through the pipeline that cultivation matrix is arranged, directly heat strawberry root ring border, backwater gets back to normal heating boiler, maintains strawberry root circle environmental temperature at 15 ~ 20 DEG C by the continuous circulation of this process; Summer, adopt the water temperature from the beginning of 20 ~ 23 DEG C, without the need to heating, directly open water pump, running water flows through the pipeline that cultivation matrix is arranged, directly lower the temperature to strawberry root ring border, backwater gets back to normal heating boiler, maintains strawberry root circle environmental temperature at 23 ~ 25 DEG C by the continuous circulation of this process.
The facility related in described method comprises normal-pressure hot-water boiler, water pump, water inlet pipe, outlet pipe, it is characterized in that: normal-pressure hot-water boiler upper end connects running water pipe, lower end connects water inlet pipe, water pump installed by water inlet pipe, each arm is directly arranged on the cultivation matrix of strawberry high-level cultivating groove, each arm one end connects water inlet pipe, and the other end connects outlet pipe, and the other end of outlet pipe is connected with normal-pressure hot-water boiler upper end.
Good effect of the present invention: one, directly the root circle environmental temperature of plant growth is regulated and controled, for the overall temperature of regulation and control greenhouse by solar heat, because the area of regulation and control reduces, therefore the difficulty regulated and controled reduces, and because of root ring border relatively stable, decrease for the energy required for temperature adjusting, but regulation and control effect improve; Two, in the winter time, directly heat temperature raising is carried out to strawberry root ring border, the temperature of strawberry surrounding environment and ground temperature are synchronously raised, be conducive to the vigor improving strawberry root system, improve the ability of Root Absorption nutrient, promote strawberry growth; In summer, directly strawberry root circle environmental temperature is lowered the temperature, the temperature of strawberry surrounding environment and ground temperature are synchronously reduced, be beneficial to strawberry carry out photosynthesis and due to be adopt enclosed cooling water circulation mode, control the increase of greenhouse humidity, reduce the phenomenon of strawberry blade face condensation dewdrop, effectively decrease the generation of strawberry damage by disease and insect.
